From 24ee53231da84a1be5ec08abebe8a2ff6aa019ca Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Wed, 22 Aug 2018 12:34:13 +0200 Subject: radv: remove dead variables after splitting per member structs Otherwise, nir_lower_clip_cull_distance_arrays might report wrong number of output clips/culls because it relies on shader output variables and some of them might be dead. This fixes a rendering issue with Dolphin and Super Mario Sunshine.
